The following describes the crimping process operation that uses above-mentioned crimping processing machine 1.At first, drive forwards oscillating cylinder 79, crimping machining tool installation bracket 21 is converted to the workpiece accepting state, as shown in figure 11.In this workpiece accepting state, crimping machining tool installation bracket 21 with respect to mould 3 big degree open place work piece W on mould 3 thereupon.At this moment, pre-crimping machining tool 33 is in by the retracted position shown in the double dot dash line among Fig. 7.In addition, workpiece W is transformed into outside plate Wo in the bottom and inner panel Wi places the state on the outside plate Wo.The marginal portion Fo of outside plate Wo is bent upwards roughly 90 °.
When workpiece W placed on the mould 3, the manipulator (not shown) transmitted and the work handgrip 115 of locating clip clamping of workpieces W on support 113.Behind this location, the manipulator (not shown) unclamps clamping to workpiece W by working clamp 117, as shown in Figure 6.At this moment, because crimping machining tool installation bracket 21 is opened wide-angle with respect to mould 3, workpiece W easily is loaded on the mould 3.Be in the crimping machining tool 31 of retracted position and pre-crimping machining tool 33 also with respect to mould 3 big degree open.
Then, from state shown in Figure 11,, clevis 85 is moved along the dextrad of Figure 11 to rear drive oscillating cylinder 79.Should moving of oscillating cylinder 79 makes lower link 71 rotate by the clockwise direction among Figure 11 around rotating back shaft 69, and upper links 75 is rotated by the counter clockwise direction among Figure 11 around rotating back shaft 73.Like this, this connecting rod 71 and connecting rod 75 form straight line in vertical direction, as shown in figure 12.
Once more, from state shown in Figure 11,, crimping machining tool installation bracket 21 is clockwise rotated around carriage connecting axle 23 to rear drive oscillating cylinder 79.Crimping machining tool 31 also is converted to the position that is in mould 3 tops.In addition, drive forwards pre-crimping machining tool slip cylinder 45, pre-crimping machining tool 33 is converted to the position state forward shown in solid line position among Fig. 7.Then, pre-crimping machining tool 33 is between the marginal portion Fo and crimping machining tool 31 of the outside plate Wo on the mould 3, as shown in figure 12.
From state shown in Figure 12, servomotor 91 drives toggle 101 shown in Figure 10.At this moment, the driving side straight line connecting rod 103 of toggle 101 counter clockwise direction of pressing among Figure 10 around the output shaft 107 of reduction gearing 93 is rotated.This makes slave end bent connecting rod 105 rotate and decline around top connecting axle 111.Like this, vertically travelling carriage 15 descends together with crimping machining tool installation bracket 21.
The decline of crimping machining tool installation bracket 21 makes pre-crimping machining tool installation bracket 35 also descend with the decline of vertical travelling carriage 15 together.Because pre-crimping machining tool 33 is installed on the pre-crimping machining tool installation bracket 35, the decline of crimping machining tool installation bracket 21 and vertical travelling carriage 15 also descends pre-crimping machining tool 33.Like this, between pre-crimping machining tool 33 and mould 3, carry out pre-crimping processing processing, as shown in Figure 1.In pre-crimping processing processing, the marginal portion Fo of outside plate Wo is transformed into about 45 ° folded state by 90 ° the folded state basically shown in Figure 11.
After pre-crimping processing processing, servomotor 91 is rotating with above-mentioned opposite direction, thereby vertical travelling carriage 15 rises together with crimping machining tool installation bracket 21.Pre-crimping machining tool 33 also rises and leaves workpiece W arrival position as shown in figure 12.In addition, the pre-left-hand of crimping machining tool 33 from this position along Figure 12 moves with withdrawal.
Carry out the action of pre-crimping machining tool 22 withdrawals by driving pre-crimping machining tool slip cylinder 45, this withdrawal makes the solid line position of member from Fig. 7 be displaced to the double dot dash line position.Crimping machining tool 33 is withdrawn from the position of workpiece W top and is transformed into the state that separates with workpiece W like this, in advance.
From this state, servomotor 91 drives toggle 101 to process mode identical in the process with above-mentioned pre-crimping, makes vertical travelling carriage 15 descend together with crimping machining tool installation bracket 21 and crimping machining tool 31.Like this, crimping machining tool 31 is to the marginal portion Fo that presses down outside plate Wo, as shown in figure 13.In other words, between crimping machining tool 31 and mould 3, carry out the processing processing of master file limit.As a result, the marginal portion Fo of outside plate Wo and the marginal portion Fi of inner panel Wi are overlapping, therefore finish crimping processing processing.
After the processing processing of master file limit, servomotor 91 produces reverse drive, and wherein, crimping machining tool 31 rises with respect to mainframe 5 together with vertical travelling carriage 15 and crimping machining tool installation bracket 21.Then, drive forwards oscillating cylinder 79 crimping machining tool 31 is rotated around carriage connecting axle 23 with respect to vertical travelling carriage 15 with pre-crimping machining tool installation bracket 35 with crimping machining tool installation bracket 21 together with pre-crimping machining tool 33, thereby be transformed into state same as shown in Figure 11.
